Yes and yes, I even replaced the pickup. It runs great for the first couple minutes and then it starts missing and gets worse with time. I could barely get back to the harbor. Fortunately I didn't sell my old MSD set up and I connectorized everything so the most difficult thing is running the power wires and re-tyrapping everything. Hot swap ignitions. I do have to reset the timing as the Daytona was set for a 36* trigger with timing locked at 34*. I'll call Daytona tomorrow.

Well Daytona discovered I had a bad coil and I figured out the new MSD pickup was bad. I think the pickup might have been a knockoff as the wire colors were wrong. Put the old pick up in and re-installed the Daytona system. I also tried some different timing. I set the physical timing to 36* BTDC and set from 0-500rpm at 36* and 1000-1500rpm to 24* and everything above 2500rpm to 34*. I enabled idle control as well to try and keep the idle to 800. I have a pretty long duration cam so idle is really tuff below 1000rpm in gear. Once I got the physical timing set, it ran better than ever. Even cold it would idle and it would never do that before even locked at 34* with the MSD. Once I had it warmed up, I tried to stall it by holding the steering to lock and it dropped to 600rpm but still ran perfect. I think the combination of lots of timing down low and idle stabilization on is the trick. It’s never run better. It’s only taken me all season to get it worked out. Well I have something to look forward to for next year.
